From 0106dc4f05231b44f54fae5d0ee42031298588bd Mon Sep 17 00:00:00 2001 From: Mark Wu Date: Wed, 9 Oct 2013 10:37:26 +0800 Subject: [PATCH] qemu-ga: Extend 'guest-info' command to expose flag 'success-response' Now we have several qemu-ga commands not returning response on success. It has been documented in qga/qapi-schema.json already. This patch exposes the 'success-response' flag by extending 'guest-info' command. With this change, the clients can handle the command response more flexibly.
